Care

Keep your tree in a warm, humid spot and ensure the soil stays consistently moist but never waterlogged. Watch for yellowing leaves which often signal overwatering or poor drainage. Protect the plant from cold drafts as it is very sensitive to chilly temperatures.

Watering
Water deeply when the top inch of soil feels dry to the touch.
Feeding
Apply a balanced fertilizer during the active growing season.
Pruning
Prune lightly in late winter to maintain shape and encourage airflow.
Repotting
Move to a larger container once the roots begin to circle the pot.

Signs it needs repotting

    Propagation
    seed, grafting
    When to plant
    spring, summer
    Overwintering
    Bring the plant indoors or into a greenhouse if temperatures drop below 10 degrees Celsius. Keep it in a bright spot and reduce watering during the cooler months.
    In containers
    It can grow in a large container of at least 50 liters, but it will remain smaller than in the ground.

    Seed propagation

    1. Clean seeds of all pulp.
    2. Soak seeds in water for 24 hours.
    3. Plant in moist, well draining soil.
    4. Keep in a warm, humid location.
    5. Transplant once the seedling has two sets of true leaves.

    Plant in a sheltered spot away from strong winds to protect the large, heavy fruits.

    • Papaya · Shares similar tropical moisture and nutrient requirements.

    Similar species
